A filename is simply a unique identifier for any file... It used to be limited to 11 characters plus a three character extension (for example computer.com) - Advances in programming now allows over 200 characters in a file name.
The maximum number of characters allowed for a file name varies by operating system. For example, in Windows, the maximum file name length is 260 characters, including the path. In contrast, most Linux filesystems allow file names up to 255 characters. It's important to note that these limits can be affected by the file system being used.
Windows 95 supported file names up to 255 characters in length.
The set of characters at the end of a file name used to identify a file type is called a file extension. It typically consists of a period followed by a sequence of letters, such as ".txt" for text files or ".jpg" for image files. File extensions help operating systems and users recognize the format and associated applications for opening the files.

The DOS (Disk Operating System) rule for file name length states that file names can be a maximum of 8 characters, followed by a 3-character file extension, commonly referred to as the 8.3 naming convention. This means that file names must be formatted as "filename.ext," where "filename" can consist of up to 8 characters, and "ext" can have up to 3 characters. This limitation applies to the older FAT (File Allocation Table) file systems commonly used in DOS environments.
